A former Kansas City man already in prison for pulling the biggest bank robbery in American history has gotten more time for eleven money laundering convictions. Ray Bowman’s new sentence of 11 years will run concurrently with the 24-year term he’s already doing for a bank robbery in the state of Washington that netted robbers almost four and a half-million dollars. He’s also doing concurrent sentences for other bank robberies. Bowman and accomplices became known as the “Trench Coat” robbers for a series of 28 robberies during the 90s.
